SHUTTER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 416,992, dated December 10, 1889.

Application filed October 2, 1889. Serial No.y 325,760. (No model.) l

To all whom, t may concern:

Be it known that I, JOSEPH L. UHEROT, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Locks or lloldfasts for Iindow- Shutters, of which the following is a full, clear, and exact description.

My invention relates to that class of de* ro vices for securing the ordinary leve-rcatcl1es or fastenings of outside Window-shutters -when closed in the fastened position, the object of which is to prevent the unfastening of the catches from the outside of the window.

It consists of an arin or lever, which is fnlcrumed to the window-sill and coupled, by means of a links-yoke or equivalent device, to the lever-catch of a window-shutter, when 2o closed and fastened in the ordinary manner, the free end of the arm or lever being located in the path of the Window-sash, so that on closing the latter the arm or lever is thereby operated t-o firmly hold the shutterecatch in the fastened position and prevent its being raised or unfastcned from the outside of the window.

On the accompanying drawings, Figure l represents a transverse section through the 3o lower parts of a window shutter or sash, the shutter being closed against the window-sill and fastened by an ordinary lever-catch with my invention applied thereto, and Fig. a sectional plan thereof taken on the line 2 2 in Fig. l.

Like letters of reference denote like parts in both figures.

ay represents the lower portion of an out- 4side window-shutter in its closed position 4o against the window-sill b, to which it is fastened by an ordinary lever-catch c. Behind and centrally in line with the catch c a preferably forked arm or lever d, having its forked ends adjacent to the catch c fnlcruined at e to the window-sill b, while its free and connected end portion, which is preferably flattenethextends across the path of the window-sash f, and is normally held at a slight upward inclination from the fulcruin e, as

5o seen in dotted lines, Fig. l, by a link or yoke g, which is coupled at its forked ends to the forked portions of the arm or lever d at a suitable distance from vthe fulcrnin e, the

other looped end of the yoke g, when the shutter a is closedand fastened, as shown, being passed over and held by the inner curved edge of the shutter-catch c.

In operation, on closing the window-sash f its lower edge descends upon the freeend portion of the forked arin or lever d, which 6o is thereby depressed radially to its fulcruin e into the position shown by full lines in Fig.

l, thereby causing the link or yoke g t-o constrain downward and firmly hold the shutter-catch cin the fastened position, so that it cannot be raised or unfastened from the outside of the window, nor until the sash fis raised from the inside of the window for releasing the arm or lever d, which, owing to the tension of the parts induced by its pre 7o vious depression, then springs back to its normal position. Then required to unfasten the shutter a, the arin or lever CZ is thrown upward on its fulcruin c and the yoke g unhitched froin the shutter-catch c.

For preventing the withdrawal endwise of the arm or lever d from its position beneath the closed sash j on the removal of the fulcrum e, the free end of the arm or lever d may be formed with an upwardly-projecting 8o lug or flange 71 which sets against the inside of the sash j'.

I claim as my inventionl. In a window-shutter fastening, the coinbination of an arin or lever fulcrumed to the 8 5 window-sill and extending across the plath of the window-sash, the said arm or lever being coupled by a link or yoke to the shutter catch or fastening, substantially as shown, and for the purpose described.

2. In a window-shutter fastening', the coinbination of an arm or lever fulcruined to the window-sill and extending across the path of the Window-sash, the said arm or lever being' coupled by a link or yoke to the shutter catch 95 or fastening and provided at its free end with a lug or fiange, substantially as shown, and for the purpose described.

In testimony whereof I have affixed my signature, in presence of two witnesses, this 18th roo day of September, 1889.
